ANTIRATTLING DEVICE FDR BRAKE-BANDS.

oaaeae.

To all whom it may concern.

Be it known that 1, JOHN EVANS, a citizen of the United States, and aresident of Utica, in the county of Oneida and State of New York, haveinvented a new and Improved Antirattling Device for Brake- Bands, ofwhich the following is a full, clear, and exact description.

The invention relates to the brake mechanism, such as is used onautomobiles and other machines, and its object is to provide a new andimproved device for preventing rattling of the brake band while themachine is running and the brake band is not in use, the device notinterfering with the application of the brake whenever it is desired todo so.

For the purpose mentioned, the brake band is attached. intermediate itsends by yielding supports, which hold the brake band normally out oicontact with the brake wheel, but allow of drawing the brake band intocontact with the brake wheel.

A practical embodiment of the invention represented in the accompanyingdrawings forming a part of this specification, in which similarcharacters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the improvement as applied to the brakeband of an automobile; Fig. 2 is an enlarged transverse section of thesame on the line 2-2 of Fig. 1; and Fig. 3 is a plan view of the same.

The brake band A shown in the drawings, is of the usual construction,and operates in conjunction with the brake wheel B 'for braking theautomobile whenever the operator manipulates the brake-operatingmechanism C for applying the brake.

The brake band A is riveted or otherwise secured, intermediate its ends,to one, two or more plates D, each provided with an angular tubularextension D, mounted to slide on a rod E, extending radially and securedto the axle F or other fixed part of the automobile.

On the rod E is adjustably secured a casing G, by the use of a set screwH, and in the said casing Gr is arranged a coil spring I, resting withone end on the casing end G and pressing with its other end against aSpecification of Letters Patent.

collar D secured to or formed on the tubular extension D of the plate D.Now by the arrangement described, the spring I presses the plate D in anoutward direction, to normally hold the brake band A out of contact withthe peripheral face of the brake wheel B. The outward movement of theplate D is limited by a stop arm E, forming an angular extension of therod E, as plainly shown in the drawings. Now when the operator actuatesthe brake-operating mechanism G for applying the brake, then the brakeband A is drawn into contact with the peripheral face of the brake wheelB in the usual manner, and the brake band A. readily carries the plate Dalong against the tension of the spring I, and when the operatorreleases the brake-operating mechanism 0, the brake band Ais'immediately moved out of contact with the peripheral face of thebrake wheel 13 and held out of contact by the action of thespring-pressed plate D, as previously explained.

Thus by the arrangement described, the brake band is not liable torattle when not in use, as it is held firmly in the dormant position orinactive position, but the brake band can be readily moved into brakingposition on the operator actuating the mechanism C, in the usual manner.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. Au anti rattling device for brake bands, comprising a fixed rodprovided with an angular arm, a plate secured to the brake band andadapted to rest against the said arm, the said plate having anextension, a casing attached to the said rod and into which extends thesaid extension, and a spring in the said casing pressing the saidextension.

2. An anti rattling device for brake bands, comprising a fixed rodprovided with an angular arm, a plate secured to the brake band andadapted to rest against the said arm, the said plate having a tubularextension provided with a collar, the said extension being mounted toslide on the said rod, a casing adjustably secured on the said rod, anda spring within the said casing and pressing the said collar.

3. In a device of the class described the In testimony whereof I havesigned my combination With the brake Wheel and the name to thisspecification in the presence of 10 brake band, 01": a rod arrangedsubstantially two subscribing witnesses. radial t0 the Wheel and havingone end fixed and the other slidably connected With the JOHN EVANS banda casing adjustably secured to the rod, Htnesses: and a spring betweenthe casing and the KATHRYN M.
